Important User Information Solid state equipment has operational characteristics differing from those of electromechanical equipment. Safety Guidelines for the Application, Installation and Maintenance of Solid State Controls (Publication SGI-1.1 available from your local Rockwell Automation sales office or online at http://www.ab.com/manuals/gi) describes some important differences between solid state equipment and hard-wired electromechanical devices. Because of this difference, and also because of the wide variety of uses for solid state equipment, all persons responsible for applying this equipment must satisfy themselves that each intended application of this equipment is acceptable.
In no event will Rockwell Automation, Inc. be responsible or liable for indirect or consequential damages resulting from the use or application of this equipment.
The examples and diagrams in this manual are included solely for illustrative purposes. Because of the many variables and requirements associated with any particular installation, Rockwell Automation, Inc. cannot assume responsibility or liability for actual use based on the examples and diagrams.
No patent liability is assumed by Rockwell Automation, Inc. with respect to use of information, circuits, equipment, or software described in this manual.
Reproduction of the contents of this manual, in whole or in part, without written permission of Rockwell Automation, Inc. is prohibited.
Throughout this manual, when necessary we use notes to make you aware of safety considerations.
WARNINGIdentifies information about practices or circumstances that can cause an explosion in a hazardous environment, which may lead to personal injury or death, property damage, or economic loss.
IMPORTANT Identifies information that is critical for successful application and understanding of the product.
ATTENTION Identifies information about practices or circumstances that can lead to personal injury or death, property damage, or economic loss. Attentions help you:
• identify a hazard
• avoid a hazard
• recognize the consequence
SHOCK HAZARD Labels may be located on or inside the equipment (e.g., drive or motor) to alert people that dangerous voltage may be present.

Pico Controller
Safety Information
Simply Pico Clever Switching and Controlling
Pico is a compact, user-friendly and low-cost controller for simple control applications. Applications range from building and domestic automation to machine and plant control. Pico has built-in user-friendly operating elements and an LCD display.
Connect Pico and draw a circuit diagram on the display by pressing the buttons on the device. Pico works with make contacts, break contacts, and relays.
Enter a circuit diagram in Pico just like it is sketched on paper. Pico has basic and advanced functions for relays, time switches and contactors, among other functions. Make changes to the circuit by pressing the buttons on the device. Time consuming rewiring is not necessary.
ATTENTION Electrical Shock Hazard
The electrical installation and commissioning work must only be carried out by suitably qualified personnel.
Do not work on the device when the power is turned on.
Observe the relevant safety regulations:
• Turn off the power
• Make sure that the device cannot be powered on again inadvertently
• Check to make sure that no dangerous voltages are present before working on the device

When you power-up Pico for the first time, you are asked to select the menu language.
Use the up and down cursor buttons to select a language. Definitions of the language abbreviations are shown below.
Press Ok to confirm your choice or press Esc to exit the menu. The unit then switches to the status display. You can also change the language setting at a later date.
If you do not set the language, Pico displays this menu and waits for you to select a language every time the unit is powered up.
TIP A brief current surge is produced when powering on the unit for the first time. Do not switch the unit using reed contacts, since these may burn or melt.

The two Pico operating modes are RUN and STOP.
• RUN: Pico processes the circuit diagram.
• STOP: Create and modify the circuit diagram.
The alternating RUN/STOP menu shows either RUN or STOP as follows:
• STOP mode active: RUN is shown
• RUN mode active: STOP is shown
Selectable Start-up Behavior

Pico Circuit Diagram Elements
Contacts
Contacts are used to modify the flow of current in the circuit diagram. Contacts in the circuit diagram are either make or break contacts. Make contacts are open when off (de-energized) and closed when on. Break contacts are closed when off and open when on.
Pico works with different contacts, which can be used in any order in the contact fields of the circuit diagram.

Analog Comparator
Available functions:
• I7 ≥ I8, I7 ≤ I8• I7 ≥ Setpoint, I7 ≤ Setpoint
• I8 ≥ Setpoint, I8 ≤ Setpoint
The analog comparator can compare voltages from 0V to 10V (setpoints “0.0” to “10.0”).
Parameter Displays for Analog Comparators
Compare inputs I7 and I8.
TIP Analog signals of sensors typically fluctuate by several millivolts. For stable switching the setpoints should differ by at least 0.2V (switching hysteresis). Do not use any relay with output energize or impulse relay coil functions.

Pico Interface Socket
The Pico interface socket, which is beneath a protective cap, accepts the optional Pico memory module, or connects Pico to a PC using the optional PC interface cable and the PicoSoft software. This allows you to copy the circuit diagrams to and from the PC and/or memory module.
Memory Module
Memory modules are available as an optional accessory. Each memory module can store a single Pico circuit diagram. Information stored on the memory module is non-volatile (the information is not lost when the power is turned off). The memory module can be used to make a backup copy of a program and/or to transfer it to another Pico controller.
Each memory module can hold one Pico program, up to 32K.
Each memory module stores:
• the circuit diagram
• all parameter settings of the circuit diagram
• system settings
1760-MM1 for all 1760-L12xxx controllers
1760-MM2 for the 1760-L18xxx controllers

3-2 Pico Interface Socket
Load or Store the Circuit Diagram
You can only transfer the program from Pico to the memory module or vice versa in the STOP mode.
DEVICE - CARD: Transfer circuit diagram and parameter settings from Pico to the memory module.
CARD - DEVICE: Transfer circuit diagram and parameter settings from the memory module to Pico.
DELETE CARD: Delete the contents of the memory module.
Available Memory Modules
The following memory modules are available as Pico accessories.
Programs including all relevant data can be transferred from the 1760-MM2B memory module to the Series B Pico Controllers. The existing 1760-MM1 and 1760-MM2 memory modules are Read-Only when used with Series B Pico Controllers. The 1760-MM2B memory module will not work with Series A Pico Controllers.
ATTENTION ELECTRICAL SHOCK HAZARD
The memory module and PC-cable socket are at the potential of L2. There is a danger of electric shock if L2 is not grounded. Do not make contact with electrical components under the socket cover.

PicoSoft
PicoSoft is an optional PC program that creates, stores, and manages Pico circuit diagrams. It transfers the circuit diagrams from the PC to Pico or vice versa using a special PC interface cable.
The PicoSoft software also includes extensive on-line Help.
To use the on-line Help, start PicoSoft and choose Contents in the Help menu. Context sensitive help is also available. Choose a menu item with the mouse and press F1 while keeping the mouse button pressed.
Software Compatibility
If you are using programming software to program the Pico controller, be sure that you are using the correct software version.
Find the Series Letter
The Series letter is printed on the side of the housing as shown.
Download the Software
You can download a free copy of PicoSoft version 6.1 from our web site. Go to http://www.ab.com/picosoft6.
For PicoSoft Pro, please contact your Allen-Bradley Distributor or Rockwell Automation representative.
ATTENTION The PC interface cable is catalog number 1760-CBL-PM02 and is available as an accessory item. Only use the Pico interface cable. Do not attempt to make your own cable as this can cause damage to the unit or present a shock hazard.
IMPORTANT PicoSoft version 6.1 or higher must be used to for the Series B Pico controller. Earlier versions of PicoSoft can only be used with Series A Pico controllers.
